Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to a cutting equipment for cold-proof composite fabrics. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to cutting equipment is also constantly improving. Fabric is the material used to make clothing. Fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. At present, cold-proof composite fabric is very popular. In the production and processing of cold-proof composite fabric, cutting equipment is needed to cut it.

[0003] The cutting equipment currently in use cannot smooth out the cold-proof composite fabric on both sides of the cutting blade when cutting it. When the cutting blade cuts the cold-proof composite fabric, the fabric is prone to wrinkling due to movement, resulting in uneven cuts and poor cutting effect, which is not conducive to the use of the cutting equipment. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: the cutting equipment currently used cannot smooth the cold-proof composite fabric on both sides of the cutting blade when cutting it. When the cutting blade cuts the cold-proof composite fabric, the fabric is prone to wrinkling due to movement, resulting in uneven cuts and poor cutting effect, which is not conducive to the use of the cutting equipment. Therefore, this invention proposes a cutting equipment for cold-proof composite fabric.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting device for cold-proof composite fabric includes a support table, a bracket fixedly connected to the support table, a placement seat slidably connected to the bracket, a rotating rod connected to the placement seat via a torsion spring, and a bearing plate fixedly connected to the rotating rod.

[0007] Two hydraulic cylinders are fixedly installed on the bracket. A cross is fixedly connected to the drive end of the two hydraulic cylinders. A cutting blade is fixedly connected inside the cross. Two sliding openings are opened on the cross. An I-shaped block is slidably arranged in each sliding opening. A T-shaped frame is connected to the I-shaped block through a first spring. A pressing wheel is rotatably arranged on the T-shaped frame.

[0008] A limiting component is fixedly installed on the cross. The limiting component includes two L-shaped plates fixedly installed on the upper surface of the cross. A horizontal plate is fixedly connected to the upper end of each T-shaped frame. The horizontal plate has a through-hole for connecting the L-shaped plates. Two pull rods are connected to the cross by two second springs. A vertical groove is provided on each T-shaped frame. One end of each pull rod is slidably connected to the corresponding vertical groove.

[0009] Preferably, each of the horizontal plates is fixedly connected to one side of a mounting rod with an L-shaped cross-section, and the two mounting rods are arranged symmetrically.

[0010] Preferably, the support platform has a slot, a support block is slidably connected in the slot, the upper surface of the support block is fixedly connected to the bearing plate, two symmetrically arranged fixing strips are fixedly connected to the bracket, and a storage box is provided on one side of the support platform.

[0011] Preferably, a reciprocating lead screw is rotatably connected to the bracket, a guide rod is fixedly connected to the bracket, the placement seat and the guide rod are slidably connected, and the placement seat and the reciprocating lead screw are threadedly connected.

[0012] Preferably, a limiting strip with a T-shaped cross-section is slidably connected to the placement seat, and a third spring is sleeved on the limiting strip. One end of the third spring is fixedly connected to the limiting strip, and the other end of the third spring is fixedly connected to the placement seat.

[0013] Preferably, a fastening pad is fixedly connected to the lower surface of the limiting strip, and the fastening pad is made of rubber.

[0014] Preferably, a servo motor is fixedly mounted on the bracket, and the drive end of the servo motor is fixedly connected to the reciprocating lead screw.

[0015] Preferably, two rotating cylinders are rotatably connected to the bracket, and a compression spring is fixedly connected to the inner wall of each rotating cylinder. One end of the compression spring is fixedly connected to a fixing sleeve, and a take-up roller is provided between the two fixing sleeves.

[0016] Preferably, each of the fixing sleeves has a clamping groove with an isosceles trapezoidal cross-section, and a rubber pad is fixedly connected to the inner wall of the clamping groove.

[0017] Preferably, the inner wall of each rotating cylinder is provided with a plurality of limiting grooves arranged in a circular array, and each fixed sleeve is slidably connected to the corresponding limiting groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The hydraulic cylinder drives the cross to move vertically downwards, while the T-shaped frame slides relative to the I-shaped block. After the horizontal plate moves upwards with the T-shaped frame, it will be completely above the upper surface of the L-shaped plate. Under the elastic force of the second spring, the pull rod slides relative to the cross, thereby driving the I-shaped block and the T-shaped frame to move along the slide. The two pressing rollers will roll against the fabric at the same time, and the distance between the two pressing rollers will increase, which can smooth the fabric. After that, the cutting blade moves down to cut the smoothed fabric, avoiding unevenness at the cut. It has a better cutting effect on cold-proof composite fabrics and is beneficial to the use of cutting equipment.

[0020] After the fabric is cut, the servo motor drives the reciprocating screw to rotate, and the placement seat moves along the reciprocating screw. The support block and the carrier plate move simultaneously. When the support block moves to the outside of the support platform and the placement seat continues to move in the same direction, the rotating rod moves against the two fixed strips. The rotating rod and the placement seat rotate relative to each other. The carrier plate rotates with the rotating rod and changes from a horizontal state to an inclined downward state, so that the fabric above the carrier plate can slide down into the storage box under the action of gravity for collection. There is no need to manually remove the cut fabric. The operation is simple and quick, which is beneficial to the use of the cutting equipment. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figures 1-8 A cutting device for cold-proof composite fabric includes a support platform 1, a bracket 3 fixedly connected to the support platform 1, a placement seat 6 slidably connected to the bracket 3, a rotating rod 24 connected to the placement seat 6 via a torsion spring 25, a bearing plate 8 fixedly connected to the rotating rod 24, two hydraulic cylinders 10 fixedly installed on the bracket 3, a cross 9 fixedly connected to the drive end of the two hydraulic cylinders 10, a cutting blade 13 fixedly connected inside the cross 9, two sliding openings on the cross 9, an I-shaped block 32 slidably arranged in each sliding opening, a T-shaped frame 19 connected to the I-shaped block 32 via a first spring 27, and a pressing wheel 11 rotatably arranged on the T-shaped frame 19.

[0032] A limiting component is fixedly installed on the cross 9. The limiting component includes two L-shaped plates 30 fixedly installed on the upper surface of the cross 9. A horizontal plate 28 is fixedly connected to the upper end of each T-shaped frame 19. The horizontal plate 28 has a through-hole for connecting the L-shaped plates 30. Two pull rods 29 are connected to the cross 9 by two second springs 31. Each T-shaped frame 19 has a vertical groove 26. One end of each pull rod 29 is slidably connected to the corresponding vertical groove 26. An installation rod 12 with an L-shaped cross section is fixedly connected to one side of each horizontal plate 28. The two installation rods 12 are symmetrically arranged. The two installation rods 12 are used to facilitate simultaneous manual control of the movement of the two horizontal plates 28 so that one end of each L-shaped plate 30 can be reinserted into the through-hole.

[0033] The support platform 1 has a slot, and a support block 14 is slidably connected in the slot. The upper surface of the support block 14 is fixedly connected to the bearing plate 8. Two symmetrically arranged fixing strips 16 are fixedly connected to the bracket 3. A storage box 2 is provided on one side of the support platform 1. A reciprocating screw 15 is rotatably connected to the bracket 3. A guide rod 20 is fixedly connected to the bracket 3. The placement seat 6 is slidably connected to the guide rod 20. The placement seat 6 is threadedly connected to the reciprocating screw 15. A servo motor is fixedly installed on the bracket 3. The drive end of the servo motor is fixedly connected to the reciprocating screw 15.

[0034] After the fabric is cut, the servo motor drives the reciprocating screw 15 to rotate, and the placement seat 6 moves along the reciprocating screw 15. The support block 14 and the carrier plate 8 move simultaneously. When the support block 14 moves to the outside of the support platform 1, the placement seat 6 continues to move in the same direction. The U-shaped rotating rod 24 moves against the two fixed strips 16. The rotating rod 24 rotates relative to the placement seat 6. Since one end of the torsion spring 25 is fixedly connected to the rotating rod 24 and the other end is fixedly connected to the placement seat 6, the torsion spring 25 deforms. After the carrier plate 8 rotates with the rotating rod 24, it changes from a horizontal state to an inclined downward state, so that the fabric above the carrier plate 8 can slide down into the storage box 2 for collection under the action of gravity. There is no need to manually remove the cut fabric. The operation is simple and quick, which is beneficial to the use of the cutting equipment.

[0035] A limiting strip 7 with a T-shaped cross-section is slidably connected to the placement seat 6. A third spring 5 is sleeved on the limiting strip 7. One end of the third spring 5 is fixedly connected to the limiting strip 7, and the other end of the third spring 5 is fixedly connected to the placement seat 6. A fastening pad 4 is fixedly connected to the lower surface of the limiting strip 7. The fastening pad 4 is made of rubber. When in use, first pull the limiting strip 7 upward, then place one end of the cold-proof composite fabric on the surface of the placement seat 6. Then remove the external force applied to the limiting strip 7. Under the elastic force of the third spring 5, the limiting strip 7 will move vertically downward until the surface of the fastening pad 4 is in close contact with the surface of the cold-proof composite fabric, thereby achieving the pressing and fixing treatment of the cold-proof composite fabric.

[0036] Two rotating cylinders 18 are rotatably connected to the bracket 3. A compression spring 21 is fixedly connected to the inner wall of each rotating cylinder 18. A fixing sleeve 17 is fixedly connected to one end of the compression spring 21. A take-up roller is arranged between the two fixing sleeves 17. Each fixing sleeve 17 has a clamping groove 23 with an isosceles trapezoidal cross-section. A rubber pad is fixedly connected to the inner wall of the clamping groove 23. Multiple limiting grooves 22 arranged in a ring array are opened on the inner wall of each rotating cylinder 18. Each fixing sleeve 17 is slidably connected to the corresponding limiting groove 22. When the take-up roller containing the cold-proof composite fabric is wound, its two ends are respectively inserted into the corresponding clamping groove 23 and are in close contact with the rubber pad. Under the elastic force of the compression spring 21, the two fixing sleeves 17 can be firmly connected to the take-up roller. The limiting groove 22 can prevent the fixing sleeves 17 and the rotating cylinder 18 from rotating relative to each other.

[0037] In this invention, the limiting strip 7 is first pulled upwards during use. Then, one end of the cold-proof composite fabric (not shown) is placed on the surface of the placement seat 6. After that, the external force applied to the limiting strip 7 is removed. Under the elastic force of the third spring 5, the limiting strip 7 will move vertically downwards until the surface of the fastening pad 4 is in close contact with the surface of the cold-proof composite fabric, thereby achieving the pressing and fixing of the cold-proof composite fabric. Then, the servo motor drives the reciprocating screw 15 to rotate, and the placement seat 6 will move along the reciprocating screw 15 and pull the cold-proof composite fabric, causing the take-up roller to rotate. When the cold-proof composite fabric moves to the appropriate position, the servo motor stops running.

[0038] Then, the hydraulic cylinder 10 drives the cross 9 to move vertically downwards. The two pressing rollers 11 are located on both sides of the cutting blade 13. After the two pressing rollers 11 move down with the cross 9, they will first contact the cold-proof composite fabric on the placement seat 6. Subsequently, the hydraulic cylinder 10 continues to drive the cross 9 to move down, and the T-shaped frame 19 will slide relative to the I-shaped block 32. Since one end of the first spring 27 is fixedly connected to the I-shaped block 32 and the other end is fixedly connected to the T-shaped frame 19, the first spring 27 deforms, and one end of the pull rod 29 slides inside the vertical groove 26 at the same time. In the initial state, one end of each L-shaped plate 30 passes through the corresponding opening. After the horizontal plate 28 moves up with the T-shaped frame 19, it then... It will be completely above the upper surface of the L-shaped plate 30. Since one end of each second spring 31 is fixedly connected to the pull rod 29 and the other end is fixedly connected to the cross 9, under the elastic force of the second spring 31, the pull rod 29 will slide relative to the cross 9, thereby driving the I-shaped block 32 and the T-shaped frame 19 to move along the slide. The two pressing rollers 11 will roll against the fabric at the same time, and the distance between the two pressing rollers 11 will increase, so that the fabric can be smoothed. After that, the cutting blade 13 will move down to cut the smoothed fabric, avoiding unevenness at the cut of the fabric. The cutting effect of the cold-proof composite fabric is better, which is beneficial to the use of the cutting equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
